带有攻击角度控制的三维制导

Three-Dimensional Guidance Law with Impact Angle Constraints

在三维空间导引动力学与运动学模型的基础上，假设目标静止，而导弹本身以恒速运动，基于李雅普诺夫稳定性理论设计了三维导弹导引律。根据实际的攻击角与设定的攻击角误差，分析和设计了期望的视线角运动学，在此基础上，给出了带有攻击角度控制的三维导弹导引律。仿真结果证明了该方法的正确性和有效性。

A three-dimensional guidance law was designed by using Lyapunov stability theory, which was based on the dynamics and kinematics of the relative motion between missile and target for missile guidance, and under the assumptions that the target was stationary, and the velocity of missile was a constant. According to the error between the real impact angle and the set impact angle, the desired kinematics of LOS （line of sight） was analyzed and designed, based on which, a three-dimensional guidance law with impact angle constraints was given. Simulation results show that the proposed method is right and effective.
